PRELIMINARY EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1215 AM EDT THU SEP 03 2015

VALID 12Z SUN SEP 06 2015 - 12Z THU SEP 10 2015


THE GLOBAL NUMERICAL MODELS ARE COMING INTO BETTER AGREEMENT ON A
SHUFFLING OF THE FLOW ACROSS NORTH AMERICA AT THE MEDIUM RANGE,
WITH A DEAMPLIFICATION AND PROGRESSION OF THE RECENT TROUGH OFF
THE WEST COAST AND RIDGE OVER THE EASTERN UNITED STATES
UNIVERSALLY INDICATED. THE ENSEMBLE MEANS ARE SIMILAR AND SHOULD
AFFORD A SAFER BET THAN THE STILL SQUIRRELY OPERATIONAL RUNS. THE
SOUTHWEST MONSOON APPEARS TO BE TRICKLING OFF, PERHAPS FOR THE
YEAR. COMMAHEAD PRECIPITATION SHOULD SLOWLY PULL OUT OF THE
NORTHERN HIGH PLAINS AS THE BIG CANADIAN CYCLONE MOVES EASTWARD.
THE ATTENDANT COLD FRONT WILL LIKELY CONTINUE TO PRODUCE SHOWERS
FROM THE CENTRAL STATES INTO THE GREAT LAKES THROUGHOUT THE
PERIOD. LINGERING EDDIES WEST OF FLORIDA AND OFF THE SOUTHEAST
COAST SHOULD KEEP THOSE PORTIONS OF THE GULF AND ATLANTIC
SHORELINES SHOWERY UNTIL ABOUT THE MIDDLE OF NEXT WEEK WHEN THE
FLOW OPENS.
